So if it does not boil water, it is not a boiler? It is only a water heater. Are you sure it is crystal clear? What I refer to as a boiler is is not what we have in a house. The carriages are heated with steam, using a one pipe system, and the steam and water is released into the atmosphere at...

Exactly, it should have the word fixed, or installed, but the approved guides are not very well written, so to use the 'A' level English I was taught at school to try and work out what they are saying, simply does not work. The English rented property law requiring inspection and testing is...

That was my thought, although was going to point at the by-pass valve. I know with TRVs we should have a by-pass valve, and I also know I can't find one on my own system. The basic system is flawed in many ways. The idea is the return water is monitored and when it gets hotter the boiler output...

The guidance document is not the law, I have found many times the approved guidance notes are wrong. However, it is really worth arguing about? As to looking up either guidance notes or the law, first you need to know where you live, the principality of Wales did not update at the same time as...

I seem to remember the river Seven and Solway Firth were considered as being far enough apart that tidal generation would work. But it was tried somewhere in France, and it seems the idea stinks literally, and they had to modify their idea and only generate in one direction as it needs the tide...

Need a bean counter.

Ups, missed the date.

Yes, I got many a goldfish off them, never lasted long. We seem to carry coal today in 5 gallon plastic cans, with the top cut-off, I watch them at the turn around, handing them up to fill the bunker. Never asked how many cwt to the mile, I think the coal comes from South America? I know the...

Yes 112 pounds. My error. As to plug in solar/battery, I am told there is a problem with a battery only, the paperwork asked size of solar array, but I have never tried to register it was all done for me.

@Madrab has shown how easy to swap the battery, so clearly that is the way to go.

In the days of tungsten lighting, bulbs were waterproof. But today bulbs are made of plastic not glass (with a few exceptions) and so we are looking at if the bulb can stop water ingress, not just the fitting. In the main, instead of stopping water ingress, we simply give it a route out, so...

Yes, agreed, how long can it go on for? Been with Octopus 10 months now, the letter tells me My calculation is less than £200 to date. I was before solar paying around £1,500 a year, at first I was with British Gas, who never did sort out payment for export, so paying them around £800 a year...

Yes, I was watching YouTube, and reading reports, which seemed to say there was no legal definition on being portable. I have always considered you must be either able to carry it, and that now seems to be 18 kg, although I remember the coal man carrying 112 pound sacks, (CWT) which are 50.8 kg...

Idea is portable uses power for less time, and to overheat needs time. The highest load both current and time is likely the tumble drier, far more than an oven, as the oven is thermostatically controlled. In my utility room, I went to great lengths to supply the washing machine and tumble drier...

In-rush if any is down to the driver design, rather than the LED, so will vary make to make.

So now gas is more expensive compared with off-peak electric.

After seeing the payment for export dropping, from 15p to 12p per kWh now it seems import also reducing.That 2p drop is really going to drop my bill, as largest load is overnight.

The old fluorescent lamp did have an inrush, and also very voltage dependent, at one time we saw voltage optimisers used to reduce the excess power used when we got high voltage, the move from magnetic to electronic ballasts, resulted in higher lumen output, and lower current, and longer life...

It is not a clearly cut figure, my roof solar will likely get the sun for longer, fitted Sept 2023 today 12.76 MWh with 6 kW panels so approx 300 kWh per month, divide by 6 times 0.8 = 40 kWh per month x 0.24p/kWh = £9.50 a month or £114 per year. So from that I would say an 800 watt panel...

We have to use the ratings of the protective device, yes I know we can draw more than 32 amp from a 32 amp RCBO, but not for an extended time. So with 40 amps the RCBO should in fullness of time trip. Fullness of time meaning before the cable overheats. There is a problem with the ring final in...
